Chromatography Technology CTS-8500 712 Rebuild Kit

Chromatography Technology CTS-8500 712 Rebuild Kit is a targeted replacement pack designed to refurbish the 712 High Pressure Valve (HPV) in WISP autosamplers, enabling reliable sample injection and consistent flow paths in LC workflows. Built to support preventive maintenance or field repairs on 712-series HPV assemblies, this kit replaces wear-prone components to restore valve sealing and motion performance. The rebuild includes essential hardware such as air seals, PTFE O-rings, PTFE washers, gaskets, spacers, port block housing O-rings, injector spool cup seals, and WISP solvent seals, all chosen to reestablish a tight, leak-free HPV assembly. The kit aligns with OEM reference 39-30-01131 for a 712 High Pressure Valve Rebuild Kit, reflecting its role as a complete refurbishment solution for the 712 valve used in Waters WISP autosamplers, and it is intended for technicians performing valve maintenance on LC systems. By renewing these components, the CTS-8500 kit supports reduced leakage, improved injection reproducibility, and extended valve service life between full replacements.
